Application filed July 19,1902. Serial No. 116,273. (No model.)

To aZ-Z whom it may concern):

Beit known that I, EMIL ROTH, a subject of the Emperor of Austria-Hungary, and e. resident of Vienna, Austria-Hungary, have invented a new and useful Self-Cooking Trigger Mechanism, of which the following is a. description.

The present invention relates to self-cocking trigger mechanism; and its object is to render the meme applicable to automatic firearms of all classes and more particularly to weapons having firing-pins.

In order to render present specification easily intelligible, reference is had to the sccornpanying drewings,in which similerleiters of reference denote similar parts throughout the several views.

Figure l is sectional elevation of the penis of the lock of automatic firearm necessary for the proper explanation of the invention, the parts in. their posi 1 of rest be fore the trigger is pulled. Fig. a. similar view show the position of the ports after the trigger and no the use been drawn ouch moment of release of the firiug'pin Fig. 3 is a. similar view showing the posi'nlcn of the parts when weapon hcngs'fir-e The invention is applicable to any weapon having a self-cocking mechanism revolver, pistol, rifle, or other firearm.

According to the present iuveubion the breech-bolt e carries the firing-pin (Z, huving its spring in the ordinsr form of construe tiou. The trigger a is pivotelly mounted at a in the well-known manner and provided with the usual trigger-spring. The scar b is pivocelly mounted at, I) and carries the springpressed pawl c, contacting with the trigger a, and the arm b adapted to engage the front surface of the lugfou the firing-pin to such an extent as to enable the firing-pin to be first cooked and then released by the said arm when the trigger is pulled. At the rear of the lug f the firing-pin d is provided with e. spring-pressed pawl g, the purpose of which will be hereinafter sen forth.

The device operates in the following manner:' Assuming the parts to be in the position shown in Fi 1-, on pulling theirige'er a the sear b will, with its arm b force the firingpin 01 back to the full-cock, and then when the parts have attained the position indicated in Fig. Q'release the same, allowing the weapon to be discharged. In the ordinary course of events the recoil would throw the pin back, with its lug f, to the rear of the upper end of the arm 12 and reset the parts ready for the nexe operation of the trigger, so that they would occupy the position shown in Fig. 1 after the cartridge had been discharged. The object or the spring-pressed pawl g on the firing-piu is to provide for the automatic re cocking oi the weapon if a cartridge hangs fire. In this case there would be no recoil, end ei'iier the trigger had been pulled and released the parts wouldoccupy the position shown in Fig. 3, with the arm I) of the'sear at the rear of the lug f of the firing-pin. If the trigger is pulled again, immediately the arm will now engage the end of the springpressed pawl 'g and will automatically redeck the firing-pin and again discharge the weapon. This operation may be repeated until the cartridge has been discharged, whereas it has hitherto been necessary in such cases to first recock the hammer or firing-pin by hand.

The construction might be varied in a. great many ways without, departing from the spirit of the present iuyeution, and the'iuvontion may easily be adapted to a. great variety of automatic and other firearms.

I claim as my invention- In e. selE-cochiug mechanism for automatic firearms the combination of alugou the firingrpiu end an arm on the sear; the two parts engaging suficicntly long to enable the firingpin to be cooked and released by a single pull on the trigger and a spring-pressed pawl to the rear of the lug on the firing-pin to engage the arm b of the sear, when the weapon hangs fire substantially as described.

In witness whereof hand in presence of two witnesses.
